The story centers on Olivia, a Chinese-American fashion designer based in New York. Years ago, she was framed by her stepsister, Sophia, who abducted her newborn twins and deceived Olivia into believing they had died shortly after birth.
Years later, Olivia meets Ethan, a single father raising five-year-old twins, Mason and Stella. They enter into a three-month contract marriage: Olivia agrees to pose as the children's mother to comfort them in exchange for a $50,000 fee.
While living together, Ethan quietly nurtures Olivia’s design talent. She overcomes numerous obstacles—including thwarting repeated schemes by Sophia—to successfully secure a spot to showcase her work at Fashion Week. Meanwhile, Olivia makes a shocking discovery: her biological twins are still alive. Ethan’s true identity as the president of Black Stone Capital also gradually comes to light.
Amidst the intertwining challenges of career, family, and romance, the couple’s feelings for each other deepen. Together, they unearth long-buried truths, ultimately achieving professional success and a joyful family reunion, leading to a fulfilling life.
